Summary: 2 minor issues
Major issues: none
Minor issues:
The Transit and Stub oif-List counts are only 2 octets. Will these
fields be large enough to contain
the totals for a large multicast distribution tree?
I agree this is likely to be an issue. Checking with the WG to see how
best to resolve this. One possibility is certainly to make them 4 octets.
Are there any alignment constraints on the options? It looks like all
the two-octet options come first
and the single-octet options come last. However, is this a
requirement for any future options that may
be defined?
They are aligned now, but I don't think we can require that for new
options. I'll add a comment on that.
Nits/editorial comments:
The descriptions of how the counts are maintained could use a little
clarification. For example,
I agree. I'll try to improve the language a bit for the below and also
for other options that look unclear.

when you say:
Transit Oif-List Count: This is filled in by a router sending a
Join/Prune message which is equal to the number of oifs (outgoing
interfaces) for the multicast route that has been joined by PIM.
This indicates the transit branches on a multicast distribution
tree (no members on the links between this router and joining
routers). This is added to the value advertised by all downstream
PIM routers that have joined on this oif. Length 2 octets.
it isn't clear what you mean by "which is equal to". Literally, you
are saying the Join/Prune message
is equal to something. I don't think that's quite right. Did you
mean "with a number that is equal to"?
Maybe, "with a number that is equal to the number of oifs (outgoing
interfaces) for the multicast
route that has been joined by PIM, plus the values advertised by all
downstream PIM routers that
have joined this oif."
